  • Patent number: 11281296
    Abstract: The purpose is to provide a tactile information conversion device, a tactile information conversion method, and a tactile information conversion program, which are usable for general purposes by presenting or sensing an arbitrary tactile feeling. In order to provide tactile information to an output unit capable of outputting physical quantities including electricity, force, temperature, vibration, and/or time and space, at least two or more of the physical quantities are selected according to a tactile feeling to be presented, tactile information for presenting the predetermined tactile feeling is generated based on the physical quantities that have been selected, and the tactile information that has been generated is output to the output unit.

  • Patent number: 10621837
    Abstract: The purpose is to provide a device, method and program for tactile information conversion, and an element arrangement structure for presenting a plurality of types of stimuli that are capable of presenting a plurality of types of stimuli at one point in a concentrated manner from different points. One of the features is to determine a first stimulation point at which a first type of tactile stimulus is generated or generate the first type of tactile stimulus at the first stimulation point via the output unit and output tactile information for generating a second type of tactile stimulus via the output unit to the output unit at a second stimulation point separated within a temporally and/or spatially predetermined threshold value from the first stimulation point of the first type of tactile stimulus that has been determined or generated by a first stimulation unit.

  • Patent number: 10100413
    Abstract: A base material is composed of a metal or ceramics, and an aluminum nitride coating is formed on an outermost surface thereof. The aluminum nitride coating is formed by impact sintering and contains fine particles having a particle diameter of 1 ?m or less. A thickness of the aluminum nitride coating is no less than 10 ?m. A film density of the aluminum nitride coating is no less than 90% An area ratio of aluminum nitride particles whose particle boundaries are recognizable existing in a 20 ?m×20 ?m unit area of the aluminum nitride coating is 0% to 90% while an area ratio of aluminum nitride particles whose particle boundaries are unrecognizable is 10% to 100%. Such a component for a plasma apparatus having the aluminum nitride coating can provide a strong resistance to plasma attack and radical attack.

  • Publication number: 20170022595
    Abstract: The present invention provides a plasma-resistant component for use in a plasma apparatus, wherein an oxide film is formed on at least part of a surface of a substrate of the component, the oxide film is a deposited oxide film formed as an aggregate of polycrystalline particles, the polycrystalline particles being formed by sinter-bonding of microparticles having an average particle size of 0.05 to 3 ?m, and the deposited oxide film has a film thickness of 10 ?m or more and 200 ?m or less and a film density of 90% or more. Due to above structure, it becomes possible to obtain a plasma-resistant component and a method of manufacturing a plasma-resistant component in which the generation of particles removed from the component is stably and effectively suppressed, and damage such as corrosion and deformation rarely occur during the regeneration process.
